This might due to the problem of headless rendering on a server.
I found a solution on sicxu/Deep3DFaceRecon_pytorch#2 and it works.

export PYOPENGL_PLATFORM=egl
cp docker/10_nvidia.json /usr/share/glvnd/egl_vendor.d/10_nvidia.json

where docker/10_nvidia.json can be downloaded from https://github.com/nv-tlabs/GET3D/blob/master/docker/10_nvidia.json

Thanks @ybbbbt for the solution!
I have also changed nvdiffrast's default backend to Cuda in the latest commit, which should work without OpenGL.

Thank you!

Seems to result in a blob for the output, not sure if related
